Error: Cannot create an object of type ...

I have a project working great locally but when I upload it to a website I get the following error:

Parser Error:

Cannot create an object of type 'MindFusion.Drawing.Brush' from its string representation 's:#FFF5F5F5' for the 'BackBrush' property.

Project is copied into a folder off the root.
Bin folder and contents copied to root folder.
Web.config copied to root folder.

Here's the diagram code:

Code
Select All
<ndiag:DiagramView ID="dgvMain" runat="server" Height="600px" Width="100%"
                    Behavior="LinkShapes" BorderColor="#999966" BorderStyle="Solid"
                    AllowInplaceEdit="true" BorderWidth="1px"
                    DelKeyAction="DeleteSelectedItems" EnableClipboard="True"
                    MaxImageSize="0, 0" NodeClickedScript="onNodeClicked" >
                <Diagram AllowSelfLoops="False" LinkBaseShapeSize="7" Bounds="0, 0, 255, 1920"
                    ShowGrid="True" AllowSplitLinks="True" AutoResize="None"
                    EnableStyledText="True" GridColor="LightSlateGray"
                    GridOffsetX="0" GridOffsetY="0" GridSizeX="3.175" GridSizeY="12.7"
                    LinkTextStyle="Rotate" RoundedLinks="True" BackBrush="s:#FFF5F5F5"
                    ShapeBrush="s:#FFFFFFFF"  />
        </ndiag:DiagramView>


Any idea what's going on?

This is something that a type converter from mindfusion.common.dll should handle. Could you verify if that assembly has been copied to the server?

yes.

The following have been copied to the bin folder:

MindFusion.Common.dll (ver: 1.2.3764.24450)
MindFusion.Diagramming.dll (ver: 5.3.5.27109)
MindFusion.Diagramming.WebForms.dll (ver: 3.1.1.27174)
MindFusion.Graphs.dll (ver: 1.1.0.16661)
MindFusion.Svg.dll (ver: 1.0.3818.19150)

JDiagram.jar file copied to the folder containing the diagram file (default.aspx)

So these are the .NET 3.5 NetDiagram assemblies, does your server run ASP.NET 3.5? Could you check if the page loads successfully if you remove the brush initializers from the aspx, and create brushes in the code-behind instead?

Ok. Getting closer.

Yes, the site is setup for .Net 3.5.

I removed the brush initializers from the aspx and added to the code-behind
Code
Select All
        dgvMain.Diagram.BackBrush = New MindFusion.Drawing.SolidBrush(Color.WhiteSmoke)
        dgvMain.Diagram.ShapeBrush = New MindFusion.Drawing.SolidBrush(Color.White)

and got a little farther.

I'm now getting this error:
Security Exception

Exception Details
System.Security.SecurityException: Request failed.

Stack Trace:

   System.Web.Compilation.AssemblyBuilder.AddBuildProvider(BuildProvider buildProvider) +99


I added write permissions to the all the folders but didn't help.

What am I missing?

thanks,

John

Could you check at what security level does your application run? It seems the server refuses to load any of our custom type converters. In this case, move the Diagram.Bounds initialization from the aspx markup to the code-behind as work-around.

The site's hosted at GoDaddy so I'm not sure what security level is setup but I removed the bounds settings from the aspx and added that to the page load as well and everything is working great now. thanks for your help!!

here's what I did for anyone else that may be having the same problem:

Default.aspx
Code
Select All
<ndiag:ShapeListBox ID="slbMain" runat="server" Style="background-color: white"
            Height="527px" Width="150px" JarLocation="JDiagram.jar">
</ndiag:ShapeListBox>

<ndiag:DiagramView ID="dgvMain" runat="server" Height="600px" Width="100%"
                    Behavior="LinkShapes" BorderColor="#999966" BorderStyle="Solid"
                    AllowInplaceEdit="true" BorderWidth="1px"
                    DelKeyAction="DeleteSelectedItems" EnableClipboard="True"
                    MaxImageSize="0, 0" NodeClickedScript="onNodeClicked" JarLocation="JDiagram.jar">
</ndiag:DiagramView>


Default.aspx.vb
Code
Select All
Imports MindFusion.Diagramming
Imports System.Drawing

Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load

        If Not IsPostBack Then
            dgvMain.Diagram.BackBrush = New MindFusion.Drawing.SolidBrush(Color.WhiteSmoke)
            dgvMain.Diagram.ShapeBrush = New MindFusion.Drawing.SolidBrush(Color.White)

            dgvMain.Diagram.AllowSelfLoops = False
            dgvMain.Diagram.LinkBaseShapeSize = 7
            dgvMain.Diagram.Bounds = New System.Drawing.RectangleF(0, 0, 255, 1920)
            dgvMain.Diagram.ShowGrid = True
            dgvMain.Diagram.AllowSplitLinks = True
            dgvMain.Diagram.AutoResize = AutoResize.None
            dgvMain.Diagram.EnableStyledText = True
            dgvMain.Diagram.GridColor = Color.LightSlateGray
            dgvMain.Diagram.GridOffsetX = 0
            dgvMain.Diagram.GridOffsetY = 0
            dgvMain.Diagram.GridSizeX = 3.175
            dgvMain.Diagram.GridSizeY = 12.7
            dgvMain.Diagram.LinkTextStyle = LinkTextStyle.Rotate
            dgvMain.Diagram.RoundedLinks = True
        End If

    End Sub
